The purpose of this study was to determine whether induction of either inspiratory muscle fatigue (expt 1) or diaphragmatic fatigue (expt 2) would alter the breathing pattern response to large inspiratory resistive loads. In particular, we wondered whether induction of fatigue would result in rapid shallow breathing during inspiratory resistive loading. The breathing pattern during inspiratory resistive loading was measured for 5 min in the absence of fatigue (control) and immediately after induction of either inspiratory muscle fatigue or diaphragmatic fatigue. Data were separately analyzed for the 1st and 5th min of resistive loading to distinguish between immediate and sustained effects. Fatigue was achieved by having the subjects breathe against an inspiratory threshold load while generating a predetermined fraction of either the maximal mouth pressure or maximal transdiaphragmatic pressure until they could no longer reach the target pressure. Compared with control, there were no significant alterations in breathing pattern after induction of fatigue during either the 1st or 5th min of resistive loading, regardless of whether fatigue was induced in the majority of the inspiratory muscles or just in the diaphragm. We conclude that the development of inspiratory muscle fatigue does not alter the breathing pattern response to large inspiratory resistive loads.
